# Numbers and Their Reversion

If you add 9 and 9 you get 18, and if you multiply 9 by 9 you get 81 (the reverse of 18). There are 2 more pairs of numbers with the same characteristics and where the result is two-digit:

24 + 3 = 27 and 24 * 3 = 72

and

47 + 2 = 49 and 47 * 2 = 94

But there is only one pair of numbers with a triple-digit result and its reversion.
